Abstract

Divulgation d'une méthode de traitement d'un minerai de sulfure polymétallique contenant de l'or et/ou de l'argent, et contenant aussi des métaux de base choisis parmi le groupe constitué du fer, de l'aluminium, du chrome, du titane, du cuivre, du zinc, du plomb, du nickel, du cobalt, du mercure, de l'étain ainsi que des mélanges de ces métaux. La méthode comprend les étapes de broyage du sulfure polymétallique pour produire des granules, d'oxydation des granules pour produire des granules oxydés, et de lixiviation au chlorure des granules au moyen d'une saumure contenant des halogènes dissous ainsi que des chlorures et des bromures.
